To all Wmm it may "concern:-

Be it knownthat I, SIDNEY A. Brivmn'o, a. citizen. of the United States, residing at Elyria, in the county Ohio, have invented certainnew and useful Telephone Apparatus, of

a specification, referdrawing My invention relates to telephones, and articularly ,to (lBSli'SE'tS. It has for its object to facilitate the connection and tjsconnectiono" the operative parls of the desk set, to'enable one standard stand to be used for several different types of instrument, to increase the economy of manufacture, and generally to improve the efficiency of the instrument. To this end I ,employ the. construction hereinafter set forth, ployrnent of a separable base plate, with cooperating parts, wbereon the coil, switch spr ngs, terminal rack, and their connections,

are mounted so as to be readily inserted into and withdrawn from the base of the stand,-

all connections with the instruxnentcircuit being automatically made in the act. The switch lever, which is carried on the upper portion or standard, acts mechanically on the springs of the monin form for ell types of instrument, the springs ZtlODfiII'BQUlZlHQ, change to alter the same from says 'i'n'agneto to a common battery telephone, or from one kind of cir-,

fully illustrated in the same My invention is; accompanying drawings, wherein the letters ofrcfcrence point out the same parts throughout.

In these drawings, Figure 1 is a vertical sectional view of the base and part of'the standard of a desk sot embodying 'rny inven- U011; Fig. 2 1s a bottom .plan -v1ew of the same. Fig. 3 isa similar view of thcremov' able base-plate, and Fig; 4 showsa modifu cation thereof.

chanical portions are all in the standard,

in the standard A, which preferably sheathed with insulating material such hard rubl'i'er, the vertical support a is inount ed attachecl its upper end to a cast'plug fitting the upper end of the standard (upon which the transmitter head is secured), and

at its lower end to a plate a by means of rivetspassing-through theoverturned loot u of the support.- Upon the support a is pivoted at a avert1cal-osc1llat1ng lever a, which at its upper end s pivoted to the hook lever (the latter being formed in the shape 0 a bell crank). is bifurcated, as shown at a in Figs. 1 and 2,

At its lower end the' lever o The'biiurcated end plays in a slot formed in theplate'a as the lever turns upon its pivot. The upper endof the lever is non nially thrown over" when the hook lever 1s depressed by the weight ,of the receiver the tension of the spring a riveted to thelug a on the support a- This spring may be made long and stilt, the use of the "standard for the purpose permittin length,

and the leverage obtainedby 'i'orming the hook and the lover a, as shown, permitting the strength.

The support owlth its plug and transm1t-' tor head at the upper endand the.hook lever parts upon it, slides bodily in aud'out In order to hold it in place when der it easily removable, spring. latch a I have provided the bent over as shown. gages e stud a set intothe a, at or near itslower end.- The latch spring; is punctured to receive the stud (1 and when it is desired to remove the vertical support and its parts from the stendards'AQall to remove the coverplate in the base, which will shortly. be described, and press back the spring afl'whosc end a," willitl'ien be exposed. -0I1 replacing the vertical parts in the tube, the springlatch will of itself rccngage the pin a, locking the parts in position- 'lhe base of this instrument is preferably formed as follows: A press [petal shell y) is shouldered around a central 'openingto fit secured at its upper end tothe support on and having its lower end a- Thislatch spring on wall of the tube u'p'on'the tube a" and lie against the screw ring a l which-is threaded thereon.

The terminal rack IQ is com posed of-ha'rd 'rubber'o'r other appropriate material, and may if desired be built tipof rubber or mica strips on 'hoth'sides cf. the 'metallic terminals 70, with an s of Fig, and the can in Fig. 3, are. mounted f '70 r overlymg metal stripk. In anyevent, I preferably provide the terminals with openings to receive the tips of conducting cords, with set-screws 1, '2, 3, 4, 5 and,6 for the purpose of clamping saidtips, 3 When complete the transmitter connects in place )y means of a threaded nut X t the lower and outer edges of its hell, the liner B has a horizontal flange, and two ver- I2 9, respecstifi'ens the whole baseperfectly; the vertical flange b of'the liner B incidentallystifl'ensthe top of the flange 5" forms or leather ring 6 which serves to formasoft pad or-deadener for-the base of the set. The nner side ef'this ring channel is formed by the flange ring b"'whose horizontal flange I) is notched at b at intervals, as best shown in Fig; 2. Against the lower face of this.

The inside face of the liner B, as shown in- Fig. 2, is. provided with several projections intended for the adjustment and securing of the base plates which I have now'descri-bed; Th'ese projections are shown at b and (1 Figsl' and 2, theformerbeing adapted for securing screws.-.- U on themis laid and se 'curedth'e detachabe base-plate. shown in jltigs'tla'nd 4 in twodif'ferent forms.

Thepes'ition'of the plate and the relative position of thebase at such time will be clearly understood by inspecting Figs. 2 and-4, thejparts then'ap peering just as they wouldiregister. When, thep'late Fig. 4 is superposed upon F1g.'2,.it
